Sending references of variables to thread c++

Sending references of variables to thread c++ - multithreading

When I'm trying to send reference to two vectors like that:
void listenMsg(int socket, vector<string>&vector, vector<int>&size){
/../
}
void letsGo(int socket){
vector<string> v;
vector<int> size;
thread(listenMsg, socket, ref(v), ref(size)). detach();
}
compiler gives me an error:
/home/volenko/CLionProjects/tcp_second_try/main.cpp:258:51: error: ‘vector’ is not a type
void listenMsg(int socket, vector<string>&vector, vector<int>&size){

void listenMsg(int socket, vector<string>&vector, vector<int>&size){

compiler says nothing. I'm worried about some kind of leaks or even worse problems which I won't be able to notice. Can somebody explain what's going on?
Compiling with:
g++ -Wall -g -std=c++17 -pthread main.cpp

I don't know about why you do or do not get a compile-time error in those two cases, but v and size are local variables in your letsGo() function. They will be destroyed as soon as letsGo() returns. That will be approximately the same time as when your listenMsg() thread starts to run.

LNK2019/2001 error when compiling a Boost project built from CMake the first time, but not the second

I have a project that uses Boost, with CMake for the build system. The first time that I try to compile the ALL_BUILD after CMake generation, it fails while linking with a LNK2019 error and 2 LNK2001 errors - but if I make any modification to the CMakeLists.txt (even just adding a space) and compile again, it works just fine.
Here's my CMakeLists.txt (Updated):
project(OurProject)
set(CMAKE_MFC_FLAG 2)
file(GLOB_RECURSE sources
*.c
*.cpp
*.cc)
file(GLOB_RECURSE headers

find_package(Boost REQUIRED COMPONENTS filesystem thread regex)
add_subdirectory(../ourLib ourLib)
target_link_libraries(OurProject

ourLib

And these are the three errors it comes up with:

Why am I still getting undefined reference errors linking a static library with CMake in Android NDK?

When building the following Android-NDK project I am getting dozens of undefined reference errors regarding missing standard library functions. I followed some basic examples of linking static libraries and restarted this project from scratch 3 times but I still can't find the issue. I am trying to use the lib_seal library that I compiled using -std=c++1z. (https://www.microsoft.com/en-us/research/project/simple-encrypted-arithmetic-library/).
The errors I am getting indicate the library is linked properly but according to many references online it cannot find -lstdc++ (One example recommending this is here: undefined reference to `std::ios_base::Init::Init()'). I have added this in my CMakeLists.txt under target_link_libraries, and I have tried editing the gradle file to include cppFlags = "-std=c++1z", "-std=c++11", "-lstdc++" etc. I have also tried adding arguments "-DANDROID_STL=c++_shared".
The following is from the closest I can seem to get this to compile and link:
CMakeLists.txt:
# Sets the minimum version of CMake required to build the native library.
cmake_minimum_required(VERSION 3.4.1)
add_library(lib_seal STATIC IMPORTED)

# Gradle automatically packages shared libraries with your APK.
add_library( # Sets the name of the library.
native-lib
# Sets the library as a shared library.
SHARED

# Searches for a specified prebuilt library and stores the path as a
# variable. Because CMake includes system libraries in the search path by

# completing its build.
find_library( # Sets the name of the path variable.
log-lib

# you want CMake to locate.

ninja: build stopped: subcommand failed.
Just a couple notes: I need to use -std=c++1z to use the SEAL library (or -std=gnu++1z), and towards the end of the gradle file I am specifically allowing only x86_64 architecture since I don't want to worry about cross-compiling anything until I get this working.

It looks like libseal was built with an older NDK using GNU's libstdc++ (gnustl in NDK parlance). GNU's libstdc++ is no longer included in NDK r18. You need to either rebuild libseal with libc++ or downgrade your NDK.

dlib error in porting Linux program in mac OS

Below errors happens in mac OS X 10.10, while trying to compile linux-made code in mac...
I located dlib as below, and it seems the compiler finds the dlib properly.
set (DLIB_INCLUDE_DIR "/usr/local/Cellar/dlib/19.15/include")
set (DLIB_LIB_DIR "/usr/local/Cellar/dlib/19.15/lib")
Is there any compatibility issue even using same dlib?

Undefined refernece when compiling a single file with g++

Whenever I compile my code, g++ returns this error message (this is just a segement. The rest is more of the same):
text.cpp:(.text+0x2b82): undefined reference to `parser(int, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)'

text.cpp:(.text+0x30d2): undefined reference to `contains(std::vector<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > >*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)'
Parser and contains are both functions I created that exist in the program. I heard this issue occurs when you do not link libraries or forgetting to link multiple files together, but I am only using one file (text.cpp) and have one library (-lncurses), and these errors occur with functions I have defined in the program.
I compile with g++ text.cpp -lncurses. I am using Fedora Linux 24 with the latest g++.
Snippet:
Functions in question:
void fight(vector<string> *i);
bool contains(vector<string> *v, string s);
bool parser(int a, string s);
void printinventory(vector<string> *i);
Contains:
bool contains(vector<string> v, string s)
{
for(unsigned int i=0; i < v.size(); i++)
{
if(v.at(i)==s)
{
return true;
break;
}
}
return false;
}
Function Calls (Both parser and contains are referenced in the first two lines of the error output at this location):
if(parser(6, stringinput) && contains(inventory, "Planck Plank") && currx == 0 && curry == 1 && currz == 2 && !planklaids) {
Any idea what this means?

I reference bool contains(vector<string> *v, string s); at the top but my function bool contains(vector<string> v, string s) does not take a pointer variable. Code was fixed when I made my function at the bottom have the parameters indicated at the top.

I just installed the newest version of Vim and CMake via brew, can anybody help me make sense of this issue?

This looks like a bug in the YouCompleteMe setup process and it is good if you report it to their issue tracker.
What makes me think so:
1) Warning at the top of your output:
Linking CXX shared library
/Users/danni/.vim/bundle/YouCompleteMe/third_party/ycmd/ycm_core.so
ld: warning: ignoring file
../clang+llvm-3.7.0-x86_64-linux-gnu-ubuntu-14.04/lib/libclang.so.3.7,
file was built for unsupported file format
2) The relevant clang version detection is here (if I am not mistaken).
And it selects the wrong clang for download (one for Ubuntu 14.04).
The logic to select clang to download is: if "APPLE" variable is defined - get mac os version if it is windows - then win version otherwise for 64 bit system use "x86_64-linux-gnu-ubuntu-14.04".
Possible workarounds:
1) If you don't need C-family completion, use ./install.py without --clang-completer flag
2) You install proper clang version manually and tell YouCompleteMe to use it.
I didn't try it, but it the command to use installed clang seems to be ./install.py --clang-completer --system-libclang.
You may already have clang installed if you have XCode. Otherwise check the full installation guide in the YCM documentation.
3) Brute force - change the YCM source to fetch the correct version. This is not very good way to solve the problem, because you will need to remove your changes before updating YCM and put them back after update, but this way you can also confirm the bug in the setup process:
Open /Users/danni/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/CMakeLists.txt
Add set( APPLE TRUE ) at the top.
Run ./install.py --clang-completer again.
Note: I didn't actually try this method, but think that it could work. If something goes wrong, try to search for other 'CMakeLists.txt' files in the ycmd folder and add set( APPLE TRUE ) to them.
